Through the wonder of Twitter we learned today of some pretty cool casting news for the Soska sisters’ latest flick, American Mary. The lovely Leah Gibson (Watchmen, The Twilight Saga: Eclipse) will be joining Katharine Isabelle (Mary Mason) and Paula Lindberg (Ruby RealGirl) as a character named Beatress Johnson.

Synopsis:American Mary is the story of a medical student named Mary who is growing increasingly broke and disenchanted with medical school and the established doctors she once idolized. The allure of easy money sends a desperate Mary through the messy world of underground surgeries, which leaves more marks on her than the so-called freakish clientele.

Written and directed by Jen and Sylvia Soska and produced by CJ Wallis (who also handles the camera, lighting, and editing duties), American Mary stars Katharine Isabelle in the titular role.
